【発明の属する技術分野】
本発明は、主として射出溶着工法であるダイスライドインジェクション(DSI工法)、ダイロータリーインジェクション(DRI工法)の使用時に用いられるポリアミド組成物に関し、ポリアミド樹脂の機械的物性、耐熱性、寸法精度、ガソリン、エンジンオイル等の耐油性あるいは、耐薬品性を損なうことなく、特に、成形時での流動改良剤の飛散を防止し、良好な流動性と機械的強度を併せ持つポリアミド組成物に関する。
【0002】
【従来の技術】
ポリアミド樹脂は、優れた機械特性を持っており、あらゆる分野の機構部品、構造部品に使用されている。産業の高度化に伴って、ポリアミド樹脂に要求される諸特性も徐々に向上し、用途も多岐に渡ってきた。
【0003】
近年、注目されている加工技術に射出溶着工法技術(DSI工法およびDRI工法)がある。この工法は、二次射出部の流動断面積が小さく、短時間にポリアミド組成物を流さなければ溶着強度が得られない事から、使用されるポリアミド組成物は、より流動性の高いものが望まれている。
【0004】
この対策として、現在良く使用されるポリアミド樹脂のベース粘度より更に低い粘度のポリアミド樹脂を使用したり、流動改良剤として、各種添加剤を使用する方法が行われている。しかし、射出溶着工法で使用する場合には、射出溶着装置内での樹脂同士の溶着により成形品を作成する方法のため、特に、流動改良剤を厳選する必要がある。これを怠ると成形品の溶着強度がバラツキ、安定な強度を得る事ができない。
【0005】
この流動改良剤として、ポリアミド樹脂に脂肪族カルボン酸系エステル(特開昭55−31803号公報)、脂肪族カルボン酸系物質(特開昭54−103460号公報)、アミド化合物(特公昭49−9618号公報)などの添加剤を配合することが提案されている。
【0006】
これらの樹脂組成物は、いずれもポリアミド樹脂ペレットに流動改良剤を添加する外部添加法であり、流動性と機械的強度は特に問題とは認められないが、射出溶着工法(DSI工法、DRI工法)前に流動改良剤をブレンド(外部添加)する工程が必要となること、さらには、添加した改良剤がペレットの外部表面に付着しているため、改良剤が飛散しやすく射出成形機に接続されたホッパードライヤーのフィルター詰まりが起こりやすいなどの問題点が指摘されていた。
【発明が解決しようとする課題】
【0007】
本発明は、前処理工程が省略でき、流動改良剤の飛散を抑え、良好な流動性と機械的強度を併せ持つ、主として射出溶着工法であるDSI工法およびDRI工法で使用されるポリアミド組成物を提供することを目的とする。
【問題を解決するための手段】
【0008】
本発明者は、上記問題点を解決するために鋭意検討した結果、特定の多価アルコールを予めポリアミド樹脂に混合すれば目的を達成できることを見出し本発明を完成させた。すなわち、本発明は融点が160℃〜320℃のポリアミド樹脂100重量部と、ペンタエリスリトールおよび/またはジペンタエリスリトール0.005〜5重量部と、繊維状充填材5〜50重量部とを含有するポリアミド組成物からなる射出溶着用材料である。
【0009】
以下、本発明について詳しく述べる。
本発明に用いられるポリミド樹脂は、ポリアミド6、ポリアミド46、ポリアミド66、ポリアミド610、ポリアミド6/12、ポリアミド11、ポリアミド12のような脂肪族ポリアミド、ポリヘキサジアミンテレフタルアミド、ポリヘキサジアミンイソフタルアミド、ポリテトラメチレンイソフタルアミド、メタキシレンジアミンとアジピン酸から得られるような芳香族ポリアミド、及びこれら共重合や混合物を挙げることができる。
さらに、本発明に好適なポリアミド樹脂として使用できるのは、融点が160℃〜320℃のポリアミド樹脂であり、ポリアミド6、ポリアミド66、ポリアミド6/66、ポリアミド6/6T、ポリアミド66/6T、ポリアミド66/6T/6I(ここでは、Tは、テレフタル酸、Iは、イソフタル酸、/は、共重合を示す)が挙げられる。
【0010】
本発明に用いられる多価アルコールは、ペンタエリスリトールおよび/またはジペンタエリスリトールである。
【0011】
本発明で使用する多価アルコールの配合量は、ポリアミド樹脂100重量部に対し、0.005〜5重量部、好ましくは、0.05〜3重量部である。0.005重量部より少ない使用量では成形時の流動性が不十分である。5重量部より多いと流動性は問題ないが、成形品の機械的強度が低下する傾向が認められる。
【0012】
多価アルコールとポリアミド樹脂を混合する方法は、特に制限はなく、通常は、多価アルコールをポリアミド樹脂に練り込み混合する。
混合装置も、特に制限はなく、一軸混練機あるいは二軸の混練機で十分である。
【0013】
また、本発明のポリアミド樹脂の機械的強度を高めるために、繊維状充填材を添加することができる。繊維状充填材としては、ガラス繊維、カーボン繊維、ワラストナイトやチタン酸カリウムウイスカー等の繊維状無機材料が挙げられる。好ましくは、ガラス繊維であり、中でも平均繊維径6〜15μm程度のものが最も好ましい。繊維状充填材の配合量は、ポリアミド樹脂100重量部に対して、5〜50重量部である。200重量部より多すぎると機械的強度も低下し、表面状態も悪くなるので好ましくない。無機充填材の添加方法は、特に制限はなく、多価アルコールと同時にポリアミド樹脂に添加しても良い。
【0014】
また、本発明の組成物にはその目的を損なわない範囲で耐熱剤、耐候剤、結晶化促進剤、離型剤、帯電防止剤、着色顔料等の機能性付与剤を用いることができる。
【0015】
本発明により得られるポリアミド組成物は、射出溶着材料に最も適しており、成形品としては、DSI工法およびDRI工法で作製される自動車部品、家電製品、電子機器用コネクター等が挙げられる。具体例としては、インテークマニホールド、エアーダクト、レゾネータチャンバー、オイルストレーナー、パワーステアリングタンク、ブレーキフルードサブタンク、リレーボックス、エコフィルター、ロッカーカバー、センサー等の機構部品、またそれらの部品からなるモジュール部品等が挙げられる。

BACKGROUND OF THE INVENTION
The present invention relates to a polyamide composition mainly used when using a die slide injection (DSI method) and a die rotary injection (DRI method), which are injection welding methods, and relates to mechanical properties, heat resistance, dimensional accuracy, gasoline, The present invention relates to a polyamide composition that has good fluidity and mechanical strength, in particular, prevents scattering of a flow improver during molding without impairing oil resistance or chemical resistance such as engine oil.
[0002]
[Prior art]
Polyamide resins have excellent mechanical properties and are used for mechanical parts and structural parts in all fields. With the sophistication of the industry, various properties required for polyamide resins have gradually improved, and the applications have been diversified.
[0003]
In recent years, the injection welding technique (DSI technique and DRI technique) is a processing technique that has attracted attention. In this construction method, the flow cross-sectional area of the secondary injection part is small, and since the welding strength cannot be obtained unless the polyamide composition is poured in a short time, it is desired that the polyamide composition used has higher fluidity. It is rare.
[0004]
As countermeasures, there are methods in which a polyamide resin having a lower viscosity than the base viscosity of polyamide resins that are often used at present is used, or various additives are used as a flow improver. However, when used in the injection welding method, it is particularly necessary to carefully select the flow improver because of the method of creating a molded product by welding the resins in the injection welding apparatus. If this is neglected, the weld strength of the molded product varies, and a stable strength cannot be obtained.
[0005]
As the flow improver, an aliphatic carboxylic acid ester (Japanese Patent Laid-Open No. 55-31803), an aliphatic carboxylic acid-based material (Japanese Patent Laid-Open No. 54-103460), an amide compound (Japanese Patent Publication No. 49-49) are added to a polyamide resin. It has been proposed to add additives such as No. 9618).
[0006]
All of these resin compositions are external addition methods in which a flow improver is added to polyamide resin pellets, and fluidity and mechanical strength are not recognized as problems, but an injection welding method (DSI method, DRI method) ) Before the process of blending (adding externally) the flow improver is necessary, and the added improver adheres to the external surface of the pellet, so the improver is easily scattered and connected to the injection molding machine. Some problems were pointed out, such as filter clogging of the hopper dryer.
[Problems to be solved by the invention]
[0007]
The present invention provides a polyamide composition that is mainly used in the DSI method and DRI method, which are injection welding methods, which can eliminate the pretreatment step, suppress the scattering of the flow improver, and have both good flowability and mechanical strength. The purpose is to do.
[Means for solving problems]
[0008]
As a result of intensive studies to solve the above problems, the present inventor has found that the object can be achieved by mixing a specific polyhydric alcohol in advance with a polyamide resin, thereby completing the present invention. That is, the present invention contains 100 parts by weight of a polyamide resin having a melting point of 160 ° C. to 320 ° C., 0.005 to 5 parts by weight of pentaerythritol and / or dipentaerythritol, and 5 to 50 parts by weight of a fibrous filler. It is an injection welding material made of a polyamide composition.
[0009]
The present invention will be described in detail below.
Polyimide resins used in the present invention include
Further, the polyamide resin suitable for the present invention is a polyamide resin having a melting point of 160 ° C. to 320 ° C., which is
[0010]
Polyhydric alcohol used in the present invention are pentaerythritol and / or dipentaerythritol.
[0011]
The compounding quantity of the polyhydric alcohol used by this invention is 0.005-5 weight part with respect to 100 weight part of polyamide resins, Preferably, it is 0.05-3 weight part. If the amount used is less than 0.005 parts by weight, the fluidity during molding is insufficient. When the amount is more than 5 parts by weight, there is no problem in fluidity, but a tendency to decrease the mechanical strength of the molded product is recognized.
[0012]
The method for mixing the polyhydric alcohol and the polyamide resin is not particularly limited. Usually, the polyhydric alcohol is kneaded into the polyamide resin and mixed.
The mixing apparatus is not particularly limited, and a uniaxial kneader or a biaxial kneader is sufficient.
[0013]
Moreover, in order to increase the mechanical strength of the polyamide resin of the present invention, a fibrous filler can be added. Examples of the fibrous filler include fibrous inorganic materials such as glass fiber, carbon fiber, wollastonite, and potassium titanate whisker. Glass fibers are preferable, and an average fiber diameter of about 6 to 15 μm is most preferable. The blending amount of the fibrous filler is 5 to 50 parts by weight with respect to 100 parts by weight of the polyamide resin. If the amount is more than 200 parts by weight, the mechanical strength is lowered and the surface state is also deteriorated. The method for adding the inorganic filler is not particularly limited, and may be added to the polyamide resin simultaneously with the polyhydric alcohol.
[0014]
The composition of the present invention is heat stabilizers within a range not to impair the purpose, weathering agent, crystallization accelerator, release agent, antistatic agent, may be used functionalizing agent such as wearing colored pigments.
[0015]
The polyamide composition obtained by the present invention is most suitable for injection welding materials, and examples of the molded product include automobile parts, home appliances, connectors for electronic devices and the like produced by the DSI method and the DRI method. Specific examples include mechanical parts such as intake manifolds, air ducts, resonator chambers, oil strainers, power steering tanks, brake fluid sub tanks, relay boxes, eco-filters, rocker covers, sensors, and module parts composed of these parts. Can be mentioned.
